Abstract

A sprinkler reducer fixing bracket that is capable of allowing a reducer to be adjusted in height, especially in a state where the reducer is coupled thereto. The sprinkler reducer fixing bracket includes a body fitted to a horizontal bar, a hook member whose one side is rotatably coupled to the body by means of a shaft member, a locking shaft disposed on the hook member and having a cam portion adapted to push the body to allow the hook member to move to a position for fixing the reducer up and down, and U-shaped first and second locking pins adapted to allow the hook member to maintain the fixed position of the reducer in the up and down directions.

What is claimed is: 
     
       1. A sprinkler reducer fixing bracket comprising:
 a body having an insertion space adapted to fit a horizontal bar thereto and a first mounting portion formed thereon; and 
 a hook member having a second mounting portion corresponding to the first mounting portion and a shaft member adapted to allow one side thereof to be rotatably coupled to the body therearound, 
 wherein the body comprises: a long hole formed slantly on one side thereof in such a manner as to pass the shaft member therethrough; a first long locking hole formed on the other side thereof; and a U-shaped first locking pin fitted to the first long locking hole, and the hook member comprises: a slant portion formed on the other side thereof in such a manner as to come into contact with one side of the first locking pin protruding from the first long locking hole; a locking groove formed adjacent to the slant portion in such a manner as to fit one side of the first locking pin thereto; a second long locking hole formed on the other side thereof; a releasing groove connected to the second long locking hole; a locking shaft disposed at the inside of the other side thereof and having a cam portion adapted to push the body and slant teeth slantly formed in one side direction; a driver groove formed on a head portion of the locking shaft; and a U-shaped second locking pin fitted to the second long locking hole in such a manner as to be locked onto the slant teeth. 
 
     
     
       2. The sprinkler reducer fixing bracket according to  claim 1 , wherein the body and the hook member are each made by bending a plate material to a shape of ‘ ’. 
     
     
       3. The sprinkler reducer fixing bracket according to  claim 1 , wherein the body has support protrusions protruding inwardly from top and underside thereof at positions corresponding to the width of the horizontal bar. 
     
     
       4. The sprinkler reducer fixing bracket according to  claim 1 , wherein the first locking pin and the second locking pin each have a bent end formed on one side thereof in such a manner as to be supported against one side of the first long locking hole and the second long locking hole and a loop portion formed on the other side thereof.
